Abstract

A linear compressor for generating a compressed gas includes two pistons (608a, 608b) and two cylinders (607a, 607b) so disposed coaxially as to face in mutually opposite directions, a shaft (603) equipped with the pistons (608a and 608b) at both ends thereof, coil springs (605a and 605b) coupled to the shaft (603), for returning the pistons moved apart from the piston neutral points to the piston neutral points, and a linear motor (613) for alternately generating compressed gas in two compression chambers (611a and 611b) by reciprocating the shaft (603) in the axial direction. Two non-linear forces exerted on the pistons by the compressed gas are generated and the phases of the forces are opposite. As a result, in comparison with a conventional construction equipped with only one piston, the motor thrust is reduced and converted to a linear thrust, and a high efficiency is achieved. Further, the size of the apparatus and vibration and noise are reduced.
